It has been argued that this decoupling provides an essential foundation for the emergence of language, in both ontogeny and phylogeny. Although language has a deep evolutionary history, whether this capacity for vocal functional flexibility also exists in the vocal systems of nonhuman animals has ...
Goodwin (1988) states that “ontogeny and phylogeny will not be understood until we have an exact description of the type of dynamic organization that characterizes the living state” (p. 103). With the renewed interest in organicism in 21st century biology (e.g., Nicholson 2014), the ...
Which of the following is an example of recapitulation theory (ontogeny repeats phylogeny)? a) canine teeth of dogs b) tadpole larva of frog c) placenta of mammals d) embryonic membranes of mammals Is multicellularity homologous or convergent in protists? Explain. ...
Two baby polar bears; part of the extensive display of ontogeny (too often missing in other museums’ exhibits). Asian elephant from Sri Lanka. Lamb birth defect. Like ontogeny, pathology was a major research interest in the original MNHN days. Wild boar birth defect. Fabulous large Indian gh...

Here we ask, what makes the behaviour persist? Is it environmental factors like climate, or food availability? Or is it factors like risk of infection or predators? Development (or ontogeny): How has the behaviour developed during the lifetime of the individual?
5. Remember that ontogeny recapitulates phylogeny. A writer and artist must develop through all the stages of human, mammal, vertebrate and so on. From a tiny embryo, you develop a spine, drop your tail, until one day you finally pick up the pencil and the stooped posture of a creative....
Embryology is the branch of biology concerned with embryogenesis, the development of the embryo from a fertilized egg cell. In its widest sense, embryology involves two aspects: 1) ontogeny, which deals with the development of an organism; and 2) phylogeny, which concerns itself with organisms ...
The other group of learning processes are relatively slow, flexible, and explicit. They depend strongly on the availability of knowledge and cognitive resources (e.g., working memory) of the individual, and they develop later in phylogeny and ontogeny. These learning mechanisms drive processes such...
The princi- pled openness is expressed, on a first level, in the marked abstention from postulating some unifying force that would govern phylogeny and ontogeny. Natural selection counts as just one among other relevant factors in evolution, and it works on various levels, from genes to ...
